Description
Die Erfindung betrifft einen Kartenleser für Karten, insbesondere Chipkarten, mit einem Schieber, der im Kartenleser über seitlich des Schiebers angeordnete Absenkführungen, welche in Einführrichtung der Karte schräg zur Kartenbahn verlaufen, geführt ist, und der, von der Karte bei der Einführbewegung mitgenommen, die Karte auf Kontakte des Kartenlesers absenkt.The invention relates to a card reader for cards, in particular Chip cards, with a slider in the card reader via lowering guides arranged on the side of the slide, which is at an angle to the card path in the direction of insertion of the card run, is guided, and that, from the card during the insertion movement taken the card on contacts of the card reader lowers.
Ein derartiger Kartenleser ist beispielsweise durch die EP-A-0 351 103 bekannt geworden. Such a card reader is, for example, by EP-A-0 351 103 has become known.
Bei diesem bekannten Kartenleser wird eine Karte mit ihrem Kontaktfeld während der Einführbewegung auf federnde Kontakte des Kartenlesers abgesenkt, damit ein Datenaustausch zwischen Kartenleser und Karte stattfinden kann. Das Absenken der Karte erfolgt mittels eines Schiebers, der in den starren Seitenwänden des Kartenlesers vorgesehenen Absenkführungen geführt ist und von der Karte, diese absenkend, beim Einführen mitgenommen wird. Die starren Seitenwände sind im Kartenleser seitlich der Kartenbahn vorgesehen, so daß sie auch der seitlichen Führung der Karte beim Einführen dienen.In this known card reader, a card with your Contact field during the insertion movement on resilient contacts the card reader lowered so that data exchange between Card reader and card can take place. The lowering the card is made by means of a slider that sticks in the rigid Side guides of the card reader provided lowering guides is guided and from the card, lowering it, at the Insertion is taken away. The rigid side walls are in Card readers are provided on the side of the card path so that they also serve to guide the card from the side during insertion.
Wenn in einen solchen bekannten Kartenleser z.B. zu Manipulationszwecken eine Karte, die eine größere Kartenstärke als normale Karten aufweist, eingeführt wird, müssen die am Schieber dann zusätzlichen wirkenden Kräfte von den Führungselementen des Schiebers aufgenommen werden. Auf Dauer kann dies zum Abbrechen der Führungselemente führen.If in such a known card reader e.g. for manipulation purposes a card that has a greater card strength than normal cards is introduced, the on Slide then additional acting forces from the guide elements of the slide. In the long run this can lead to the guide elements being broken off.
Es ist daher die Aufgabe der Erfindung, bei einem Kartenleser der eingangs genannten Art solche auf den Schieber beim Absenken wirkenden Kräfte besser aufnehmen zu können.It is therefore the object of the invention in a card reader of the type mentioned in such a slide Lower absorbing forces better absorb.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Absenkführungen an einem die Kartenbahn übergreifenden, federnd gelagerten Arm vorgesehen sind. Der Arm kann z.B. einseitig, vorzugsweise an seinem in Einführrichtung vorderen Ende, gehäuseseitig befestigt sein.This object is achieved in that the Lowering guides on a resilient spanning the card path supported arm are provided. The arm can e.g. on one side, preferably at its front in the direction of insertion End, be attached to the housing.
Der mit der Erfindung erzielte Vorteil besteht darin, daß der federnd gelagerte Arm die auf den Schieber wirkenden Kräfte durch Verschwenken leicht aufnehmen kann. Vorzugsweise sind die Absenkführungen in den Seitenwänden einer Aussparung im Arm vorgesehen. Der Arm kann z.B. als eine Gehäusezunge ausgebildet sein.The advantage achieved by the invention is that the spring-loaded arm acts on the slide Can easily absorb forces by swiveling. Preferably are the lowering guides in the side walls of a recess provided in the arm. The arm can e.g. as a housing tongue be trained.
Bei vorteilhaften Ausführungsformen der Erfindung übergreift der Arm die Karte etwa mittig, so daß die auf den Schieber wirkenden Kräfte gleichmäßig verteilt auf beide Führungen des Arms übertragen werden.In advantageous embodiments of the invention overlaps the arm of the card approximately in the middle, so that the slider acting forces evenly distributed on both guides of the arm.
Wenn die Breite des Arms schmaler als die Breite der Karte ist, können seitlich des Arms weitere Komponenten des Kartenlesers angeordnet werden. Dadurch ist eine weitere Miniaturisierung des Kartenlesers möglich.If the width of the arm is narrower than the width of the card other components of the card reader can be found on the side of the arm to be ordered. This is another miniaturization of the card reader possible.
Bei bevorzugten Ausführungsformen der Erfindung übergreift der Arm die Kartenbahn im Bereich der Kontakte des Kartenlesers. Für den Datenaustausch ist es ausreichend, wenn die Karte zumindest im Bereich ihres Kontaktfeldes mittels des Schiebers mit definiertem Anpreßdruck auf die Kontakte des Kartenlesers abgesenkt wird. Vorzugsweise entspricht in diesem Fall die Breite des Schiebers und damit auch die Breite des Arms etwa der Breite des auf der Karte vorgesehenen Kontaktfeldes, also bei normalen Chipkarten, wie z.B. bei einer Telefonkarte, etwa einem Viertel bis Fünftel der Kartenbreite.In preferred embodiments of the invention overlaps the arm the card path in the area of the contacts of the card reader. For data exchange it is sufficient if the Card at least in the area of your contact field using the Slider with a defined contact pressure on the contacts of the Card reader is lowered. Preferably corresponds to this Fall the width of the slide and thus also the width of the arm approximately the width of the contact field provided on the card, with normal chip cards, e.g. at a Telephone card, about a quarter to a fifth of the card width.
An dem in Einführrichtung hinteren Ende des Arms kann ein Leitsteg vorgesehen sein, mittels dem auch eine in Einführrichtung gekrümmte Karte in die korrekte Kartenbahn gelenkt wird.At the rear end of the arm in the direction of insertion, a Guide rail can be provided, by means of which also in the insertion direction curved card directed into the correct card path becomes.
